The singer has been engaged to his childhood sweetheart Amber Cochran since last year (14) and they are due to wed this summer (15), but the couple has now rejigged the date of the big day after Gilbert let it slip.

He admits he "screwed up" by revealing the date publicly, but tells the wedding is still "coming up real soon".

The nuptials will take place on a brief break from his U.S. tour with Kenny Chesney, and he will be going back on the road after the honeymoon.

Gilbert says, "I will be pulling up to the wedding, like, sliding in my driveway sideways from the road. But after that we get to go away for seven or eight days, so I'm really excited about that."

Reports suggest the wedding will take place in mid-June (15).
